WINDOW-OPERATING DEVICE.

Specification of Letters Patent.

Application filed Isebruary 9, 1914. Serial No. 817,442.

To all whom it may concern:

Be it known that I, JOHN DAWSON, a citizen of the Dominion of Canada,and a resident of Walkerville, in the county of Essex and Province ofOntario, Dominion of Canada, have invented a new and ImprovedWindow-Operating Device, of which the following is a specification.

, This invention relates to means for swinging windows, shutters anddoors hinged on horizontal pivots, preferably along their upper edges,although the pivots may be positioned anywhere else with reference tothe such closures, and its object is to provide a device of thischaracter which shall be simple in construction, positive and simple inoperation, and whose manufacturing cost shall be low.

This invention consists of a lever connected at one end to a window orother closure and which is pivoted intermediate its ends in a verticalguide so that its pivotal point may move up and down, together withmeans-for moving the opposite end of the lever, up and down at will.

This invention also consists in a slotted bar connected to the freeendof the operating lever, a wheel provided with teeth that may enter theslots in the bar, and means to support and turn said wheel to swing thelever up and down, together with means for guiding the slotted bar inengagement with said wheel.

In the accompanying drawings, Figure 1 is an inside elevation of a.window operating installation embodying this invention. Figs. 2 and 3are sections on the line 2-2 of Fig. 1 showing the window in twopositions. Fig. 1 is a section on the line A-l of Fig. 3. Fig. 5 is a'section on the line 5-5 of Fig. 2. Fig. 6 is an elevation of thesupport for the operating shaft.

Similar reference characters refer to like parts throughout the severalviews.

The construction of the window frame, of the window, or the means forsupporting the window in the frame form no part of this invention. Thewindow and its frame may be of any desired character and the window maybe pivoted along a horizontal line at any desired distance from itslower edge. In the drawings vertical pillars 1 are shown adjacent thelintels 2 and sills 3 of the window frames. Hinges 4 are shown connectedto the lintels 2 and the window sashes 5, but any other construction maybe employed. Extending between the lintels and sills, and connectedthereto in any desired manner, are the guides 6 for the pivots of theoperating levers. One manner of constructing and securing the guidesconsists in fastening channels 7 against angle bars 8, which, in turn,are connected to the lintels and sills by means of corner irons 9.

The operating levers 11 are preferably provided with pivot pins 12 whichcarry anti-friction rollers 13, slidably in the channels 7. Pivot blocks14 may be connected to any desired portions of the window sashes at anydesired distance from the ends there of, and to these blocks, the levers11 connect. Secured to the pillars 1 are any desired number of bearings15. for the shaft 16, preferably a tube, while bars 17 may be secured tothe sills 3, if desired, to carry the shaft intermediate the bearings15. On this shaft may be secured any desired number of toothed wheels18,preferably in the form of a plate of sheet steel formed with properteeth, and mounted on the sleeve 19, having a flange 20. A ring 22 maybe shrunk onto or otherwise secured to the sleeve 19 to hold the toothedplate in position.

A pin 23 may be employed to connect a channel bar 24 to the inner end ofeach operating lever, which channel bars are formed with slots 25 toreceive the teeth of the wheels 18. Guide plates 27 mounted between arms28 which are pivoted on the shaft 16, prevent thechannels from swingingaway from the wheels 18. While this shaft 16 may be turned in anydesired manner, it may be preferable to secure a bevel gear 30 thereto,which meshes with a bevel gear 31 on the upper end of a vertical shaft32. At the floor or other position where the crank 33 can be easilyreached, ,a shaft 3 1 may be mounted, on which, besides the crank, maybe secured the bevel gear 35 which meshes with the bevel gear 36 on theshaft 32. It will be understood that this invention is not limited tothis type of gearing for turning the shaft 16. v p The operating leverswill be in the position shown in Fig. 2 when the window sashes areclosed. To open the window sashes the shaft 16 is turned to the left,pulling down the bars 24 and the pivots 12, thus forcing out the lowerends of the sashes. When the parts reach the position shown in Fig. 3,the line of the thrust of the sashes along the levers 11 will be sonearly at right allgles to the guides 6, that very little stress on theslotted bars 24 will hold the parts in position. Suflicient stress isusually supplied by the plates27 which fall and grip the bars 24 below aline normal thereto from the center of the shaft 16. These guide plates27 therefore also constitute locking evices for the window operatingmechanism.

The number of window operating levers 11 will depend largely upon thelength of the sashes, it being advisable to space the levers about tenfeet apart for long sashes and to place one lever in the middle of eachshort sash, although this mechanism will also operate properly when thelevers 11 connect to the ends of short sashes. The'proportions and otherdetails can all be changed without departing from the spirit of myinvention as set forth in the claims. While this device has beendescribed as connected to a window sash, it will be understood that itis equally applicable to any other closures mounted on horizontalpivots."
